What is the Logic Ladder Application? 

The Logic Ladder application contains two activities: 

• In Factor, you determine the prime factorization of numbers 
by selecting the correct bases and exponents. 

• In Classic, you order four to six different shapes, determining 
the correct shapes in the correct order in less than nine 
steps. Clues give you an idea of how close you are to the 
correct sequence. 

The Logic Ladder application is a concept application that Tl 
wants to share with our customers, educators, and students 
before the product definition and testing are complete. It is an 
alpha software version, and as such, it may contain 
imperfections, or the coding may be incomplete. 

Tl invites your feedback concerning the functionality and 
educational value of the Logic Ladder application. Please send 
your comments and questions to concept@list.ti.com.

Scoring 

The Logic Ladder application tracks the number of wins and 
losses you have accumulated for both of the activities. Scores for 
the activities are combined. For example, if you completed the 
Factor activity giving five correct answers and two incorrect 
answers and also completed the Classic activity giving three 
correct answers and one incorrect answer, the score would show 
WINS: 8 LOSSES: 3. 

Viewing and Resetting the Score 

You can view your score at any time by returning to the main 
menu and selecting VIEW STATS. 

To reset the score, return to the main menu, and select 

CLEAR STATS. 



TI-73 / TI-83 Plus Logic Ladder Page 8 



Completing the Factor Activity 

The Factor activity lets students practice factoring numbers into 
the product of primes. 

In the Factor activity, a random number with the prime 
factorization of the form A x *B Y is generated. A and B are the 
prime bases; X and Y are the powers of the prime bases. You 
determine which values for A, B, X, and Y create the correct 
prime factorization of the number. 

1 . From the main menu, select FACTOR. The factor menu is 
displayed. 

2. Select START to display the first number to factor. The arrow 
is at A. The default selections for A, X, B, and Y are 
highlighted.

Completing the Classic Activity 

The Classic activity lets students practice logic and pattern 
recognition skills to determine the order of a set of geometric 
shapes in nine or fewer tries. After each try, clues indicate the 
number of correct shapes and the number of shapes that are in 
the correct order. Activity settings control the number of shapes 
(4 - 6) and whether shapes can be repeated. 

1 . From the main menu, select CLASSIC. The classic menu is 
displayed. 



Tip 



The default settings are 

four shapes 

shapes can be repeated 



2. Select START to display the first problem. The first shape is 
highlighted. 




TI-73 /TI-83 Plus Logic Ladder 



Page 12 



3. Press or H until the shape that you want to select is 
displayed. 




4. 



Note 



Press to move to the second shape or press I enter I to 
submit your answer and display clues about the correct 
answer. 

After you press I enter I , you have completed that try. 



A line indicates that 
one shape is 
correct, but is not in 
the correct location. 




The activity can have 
four, five, or six shapes. 
The shapes displayed at 
the top of the screen are 
those that could be part 
of the solution. 



A solid square 
indicates that one 
shape is correct and 
that shape is in the 
correct location.

5. Use your logic skills to determine the pattern of the shapes in 
as few tries as possible. 



Note 



You can use up to nine tries to determine the shape pattern. 



I 



When you determine the correct shape pattern, the clues 
show that all of the shapes are in the correct location, and 
GOOD JOB! is displayed at the bottom of the screen. 

6. Press any key to display your cumulative score. 



Notice that the order 
of the clues is 
insignificant. These 
two squares do not 
indicate that the first 
two shapes are 
correct, but that two of 
the four shapes are 
correct and are in the 
correct location.
